How do you replace the driver side headlight low beam bulb on a 2004 Mazda 6?

Answer 1

The driver's side low beam headlight is slightly easier to replace than the passenger side. The owner's manual states the dealer must replace this bulb, but it can be done yourself if you are handy. The main problem is limited access due to the crowded engine compartment. A flashlight and small mirror may be helpful, but no tools are needed. You need to purchase a replacement H1 55 watt halogen bulb. The low beam light is located closest to the fender. First remove the cover of the fuse box to give you more room to work. It is located in front of the battery. In front of the fusebox and partially hidden under the fender, you will see a circular hatch. It should be immediately behind the low beam headlight. Turn this hatch 1/8 of a turn counter clockwise (when you are looking at it from the rear). It may be a bit tight. Once you've turned it, it should come off when you pull it. Note the orientation so that you will be able to replace it when done. Inside, you will see a wire leading to the lamp. There is a clip on the fender-side of the wire that holds the lamp in place. Push in and toward the passenger side to release the clip (this takes a bit of effort). It will then swing upward and the lamp will be released. Pull the lamp straight out of the housing. Note the orientation of the lamp in the housing so you know how to put back the new one. Remove the burnt lamp by pulling it off the plug and replace it with the new one. Be sure not to touch the new lamp with your bare fingers (latex gloves work well). Now reinstall the lamp in the housing, swing the clip back down until it locks and screw the circular hatch back on. Don't forget to put the fusebox cover back on!
